Question Details

The area bounded by the curve 2x² + y² = 2 is

Options

A

π sq. units

B

√2π sq. units

C

π2 sq. units

D

2π sq. units

Correct Answer :

√2π sq. units

Solution :

The given equation of the curve is:
2 x2 + y2 = 2

To identify the curve, we can rewrite the equation in standard form by dividing both sides of the equation by 2:
2 x2 2 + y2 2 = 2 2
This simplifies to:
x2 1 + y2 2 = 1
Or in the standard form of an ellipse:
x2 12 + y2 ( 2 ) 2 = 1

This is the standard equation of an ellipse of the form:
x2 a2 + y2 b2 = 1
Comparing the two equations, we obtain the semi-axes of the ellipse:
a = 1
and
b = 2

The standard formula for the area (A) enclosed by an ellipse is given by:
A = π · a · b

Substituting the values of a and b into the area formula:
A = π · 1 · 2
This simplifies to:
A = 2 π  sq. units

Thus, the area bounded by the curve is indeed 2π square units.
